ATTACHMENT FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 367,784,dated August 9, 1887.

' Application filed December 13, 1886. Serial No. 221,409. (No model.)

To all whom it may concern.-

Be it known that I, JACOB S. BROWN, a citizen Vof the United States, residing at Carlisle, in the county of Cumberland and State of Pennsylvania, have invented certain newand useful Improvements in Attachments for Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled Io in the art to which it-appertains to make and use the same.

` My invention relates to attachments for steam-engines; and it consists in the construction and arrangement'of the parts of the same, I 5 which will be more fully hereinafter described,

and pointed out in the claims.

One object of my invention is to provide means for reversing the motion of the engine, or, by a change in the position of the parts of 2o the same device, to open and close the, throttlevalve, or produce thetwo functions simultaneously, as may be required and desired.

A further object of my invention is to provide a device adapted to be operated tosimultaneously reverse the engine or open and close the throttle-valve, which is simple and effective in its construction and operation, easily handled and readily understood, strong' and durable, positive in its desired result, and

5o comparatively inexpensive in its manufacture.

I attain these objects by the mechanism illustrated in the accompanying drawings,wherein like figures of reference indicate similar parts in the several views, and in whieh Figure 1 is a side elevation of a suitable frame-work mounted upon wheels, showing a boiler and vertical engine and my improved device in relative connection therewith. Fig.

2 is a detail view in perspective of my im- 40 proved attachment. y

This attachment is adapted for use in connection with any form of machine or engine as may be desired, but is more especially applicable for use in connection with my improved well drilling and boring machine, ap-

plication for which was filed July 12, 1886, Serial N o. 207,804.

In the drawings, 1 represents a framework, of any suitable construction and mounted on 5o or propelled by other means than those illustrated in the drawings. In one portion of this Secured to one portion of the side of the 6ok framework 1 are two uprights, .7 7, which support a metallic rod, 8, which is provided with a stud or pin, 9. rIhe one end of said rod is constructed to pass into an aperture in a hand-wheel, 10, secured to one end of a sleeve, 12,on said rod, and the other end provided with a bevel-gear, 11; Mounted upon the rod S is an elongated sleeve, 412, having a slot, 13, formed therein, throughrwhich th'e studA or piu 9 on the said rod 8 protrudes flush with the 7o outer surface of the said elongated collar.-

vThis sleeve 12 has a sliding movement on the rod 8, and is adapted for a purpose which will be more fully hereinafter described.

Formed integral with or otherwise secured to one portion of the sleeve 12 is a recessed collar, 13', which is adapted to receive one end .of a small rod, 14, which is looped around the recessed collar 13 at one end, and thence passes down under the frame-work and suit- 8o ably connected thereto, and is att-ached to the reversing-lever of the engine in any suitable manner. By drawing or pulling on the handwheel l0 the sleeve 1.2"slides outward on the rod 8, and such a motion is imparted to the lever, to which the rod 14E is connected, as to reverse the engine. This is due to the fact that the collar 13 is moved from its normal position, and consequently the lever is shifted or drawn toward the hand-wheel 10. Vben the hand- 9o Wheel 10 is pushed back again, the rod 14 resumes its normal position and the reversinglever is thrown back and the engine caused to run as before being reversed. On the end of the rod opposite tothe one adjacent to the hand-wheel 10 a bevel-gear, 11, is mounted, which is adapted to mesh with a relativelysituated bevel gear, 16, mounted on an inclined rod, 17, at the upper end of which a bevel-gear,y 1S, is mounted, which in turn 10oY which is of any desired construction, but preferably in the form of a two-way valve. ly turning the handwheel the motion imparted thereby is transmitted through the rod 8 and the gear-wheel 15 on the opposite end thereof to the gear 16 on the lower end of rod 17, and from thence to the gear 1S, to gear 19 on the valvestem 20, and thus open er close the valve 5 as the hand-wheel 10 is turned, and govern the ilow of the steam to and from the engine. rlhe stud or pin 9, passing through a slot, 13, governs the extent to which the elongated sleeve 12 may be withdrawn and pushed back, the two ends of the slot bearing against the stud or pin in either position. The slot 13 is constructed of such length as to allow the reversing-lever to be drawn or pushed from one side to the other to such a distance -as to j ust produce the desired result.

This device or attachment is speciallyy intended and applicable for use in connection with a well-drilling machine to regulate the raising or lowering of the drill and preventing accident to life and machinery, which frequently occurs, due to the heretofore uncontrollable action of the drill, especially when being raised to the surface.

It is obvious that slight variations in the construction and arrangement of the several parts of the device could be made and substituted for those shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an attachment for engines, theeombination, with the boiler, engine, and feedpipe in connection therewith, of a rod, and an elongated sleeve partially incasing said rod, said parts having connection with the throttle-valve and engi ne-reversing rod or lever,res1' eetively, and constructed to be operated together or independently, substantially as described.

2. In an attachment for engines, the eombination, with the boiler, engine, and feed-pipe in connection therewith, ofstandards mounted on one side of a suitable support-ing framework, a rod mounted and supported by said standards, having' suitable connections with the throttle-valve, an elongated sleeve snrrounding a portion of said rod, having a rod running therefrom to the reversing-lever of the engine, and ahand-wheel for operating the several parts, substantially as described.

3. ln an attachment for engines, the combination, with the boiler, engine, and feed-pipe connected therewith, of standards mounted on one side of a. suitable supporting framework, a rod having a stud-pin thereon, mounted in and supported by said standards, and having gearing meshing with relatively-situated gearing on an inclined rod ruiming to and connecting with the stem of a throttle-valve by means of suitable gears, an elongated sleeve having a slot therein mounted upon said rod, the stud-pin of which engages with the slot in said sleeve, a recessed collar integral with or secured to said elongated sleeve, a rod or level' engaging said recessed collar and extending down under the frame-work, and adapted to be attached to the reversing-level' of the engine, and a hand-wheel for operating the, several parts, substantially as described.

ln testimony whereof l affix my signature in presence of two witnesses.

JACOB S. BROWN.
